Verfahren zur Herstellung eines Anschlußelementes für die Verbindung von LichtleitkabelnProcess for the production of a connection element for the connection of fiber optic cables
Die Erfindung betrifft ein dem Oberbegriff des Patentanspruches entsprechendes Verfahren. Aufgabe der Erfindung ist es anzugeben, wie die Enden von Lichtleitkabeln bzw. deren Lichtleiter auf einfache und wirkungsvolle Weise innerhalb einer Hülse so zentriert befestigt werden könne, daß sie als Anschlußelemente verwendbar sind. Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Patentanspruches angegebenen Maßnahmen gelöst.The invention relates to a method corresponding to the preamble of the patent claim. Object of the invention it is to be indicated how the ends of fiber optic cables or their fiber optic cables in a simple and effective way can be fastened so centered within a sleeve that they can be used as connecting elements. These Object is according to the invention by the characterizing Part of the claim specified measures resolved.
Durch Anwendung des Verfahrens lassen sich Anschlußelemente fertigen, die einfach und billig in der Herstellung sind und sich außerdem durch eine präzise Zentrierung ihrer Lichtleiter auszeichnen.By using the method, connecting elements manufacture that are easy and cheap to manufacture and are also characterized by precise centering their light guides.
Die Erfindung wird anhand von Zeichnungen wie folgt näher beschrieben. In den Zeichnungen zeigt:The invention is described in more detail with reference to drawings as follows. In the drawings shows:

In den Fig. 1 und 2a bis 2c ist ein Anschlußelement dargestellt, das aus einer im wesentlichen zylindrischen Hülse 11 besteht. Diese Hülse enthält einen Lagerstein wie er bei Uhren gebräuchlich ist und außerdem dient sie zur Aufnahme eines kunststoffummantelten Lichtleitkabels 13. Zuerst wird die Hülse 11 auf die Erweichungstemperatur des aus Kunststoff 15 bestehenden Kabelmantels erhitzt und dann schiebt man das Lichtleitkabel 13 soweit in die Hülse 11, bis es am Lagerstein 12 zur Anlage kommt. Weiterer Druck auf den Kabelmantel verformt nun den erweichten Kunststoff 15 und läßt den Lichtleiter 16 durch die Pohrung 17 des Lagersteines 12 hindurch an der verbindungsseitigen Stirnfläche der Hülse hervortreten. Dieser Vorgang wird mittels einer Einsenkung 18 des Lagersteines 12 erleichtert, welche den Lichtleiter 16 in die Bohrung 17 einführt.In Figs. 1 and 2a to 2c, a connecting element is shown, which consists of a substantially cylindrical Sleeve 11 is made. This sleeve contains a jewel as it is common in watches and it is also used for receiving a plastic-sheathed light guide cable 13. First, the sleeve 11 is heated to the softening temperature of the cable jacket made of plastic 15 is heated and then the light guide cable 13 is pushed so far into the sleeve 11 until it comes to rest on the bearing block 12. Further pressure on the cable jacket is deformed Now the softened plastic 15 and lets the light guide 16 through the Pohrung 17 of the bearing block 12 through protrude on the connection-side face of the sleeve. This process is done by means of a depression 18 of the bearing block 12, which introduces the light guide 16 into the bore 17.
In diesem Stadium des Herstellungsverfahrens hat der fließende Kunststoff 15 des Lichtleitkabels 13 die Bohrung 19 der Hülse 11 so ausgefüllt, wie es in Fig. 2c dargestellt ist. Nun wird die Hülse 11 abgekühlt, so daß der Kunststoff 15 aushärtet und hierbei das Ende des Lichtleitkabels 13 in der Hülse 11 befestigt.At this stage of the manufacturing process, the flowing plastic 15 of the light guide cable 13 has the Bore 19 of the sleeve 11 is filled as shown in Fig. 2c. Now the sleeve 11 is cooled, see above that the plastic 15 hardens and in this case the end of the light guide cable 13 is fastened in the sleeve 11.
Die weiteren Verfahrenßschritte der Bearbeitung des Lichtleiterendes veranschaulichen die Fig. 3a bis 3c. Das hervorstehende Ende des Lichtleiters 16 wird 1>H spielsweinr mittels eines Drahtschneiders dicht am Lagerstein 12 abgetrennt und das Schnittende in einer Flamme geschmolzen, bis sich ein Tropen bildet, der sich mit der äußerenThe further process steps for processing the light guide end Figures 3a to 3c illustrate. The protruding end of the light guide 16 becomes 1> H spielsweinr cut off close to the bearing block 12 by means of a wire cutter and melted the cut end in a flame, until a tropic forms that merges with the outer

konischen Ansenkung 20 der Bohrung 17 des Lagersteines verbindet. Mittels eines aus neutralem Werkstoff bestehenden Werkzeuges, wie beispielsweise Kohle, wird der geschmolzene Tropfen gegen den Lagerstein und hierbei in die Form eines Nietkopfes gedrückt (Fig. 3b). Anschließend wird das Lichtleiterende nach seinem Erkalten feingeschliffen und fluchtend mit dem Lagerstein poliert wobei ein kleiner Kegel 21 übrig bleibt, der in der Ansenkung sitzt und den Lichtleiter symmetrisch in der Bohrung 17 zentriert.conical countersink 20 of the bore 17 of the bearing block connects. Using a tool made of a neutral material, such as coal, is the molten drop is pressed against the bearing block and in the process in the shape of a rivet head (Fig. 3b). The end of the light guide is then finely ground after it has cooled and is flush with the bearing block polished leaving a small cone 21, which sits in the countersink and the light guide symmetrically in the bore 17 is centered.
In Fig. Ί ist ein alternatives Beispiel der Hülse dargestellt. Diese Ausführung ähnelt der in den Fig. 1 bis gezeigten, aber hier ist im rückwärtigen Bereich der Hülse 11 innen eine ringförmig umlaufende Rippe Ί1 angeordnet, die den erweichten Kunststoff in der HUlsenbohrung zurückhält.In Fig. Ί an alternative example of the sleeve is shown. This embodiment is similar to that shown in FIGS Sleeve 11 has an annular circumferential rib Ί1 arranged on the inside, which holds back the softened plastic in the sleeve bore.
